First structurally characterized complex of an acyclic tellurated Schiff base [4-MeOC6H4TeCH2CH2N=C(CH 3)C6H4-2-OH (L1H)] having metal-tellurium bond; Synthesis and crystal structure of [PdCl(L1)]

Acyclic tellurated Schiff base [4-MeOC6H4TeCH 2CH2N=C(CH3)C6H4-2-OH (L1H)] has been synthesized by reacting 2-(4-methoxyphenyltelluro) ethylamine with o-hydroxyacetophenone. The L1H on reaction with Na2PdCl4 forms a complex [PdCl(L1)] in which the tellurated Schiff base coordinates in a tridentate mode. The proton and carbon-13 NMR spectra of L1H and the complex are characteristic. The single crystal structure of the complex is solved. The Pd-Te, Pd-Cl, Pd-O and Pd-N bond distances are 2.504(1), 2.290(4), 2.03(1) and 2.01(1) ?, respectively.

Tellurated Schiff bases formed from {2-[(4-methoxyphenyl)telluro]ethyl} amine and bis(2-aminoethyl) telluride with o-hydroxyacetophenone: Synthesis and complexation reactions with HgII, PdII and RuII - Crystal structures of the ligands, [Ru(p-cymene)Cl{A}]Cl·H2 O and [RuCl{L2}] (see abstract)

{2-[(4-Methoxyphenyl)telluro]ethyl)amine and bis(2-aminoethyl) telluride on treatment with o-hydroxyacetophenone gave the Schiff bases 4-MeOC 6H4TeCH2CH2N= C(CH 3)C6H4-2-OH (L1) and 2-HOC 6H4(CH3)C= NCH2CH 2TeCH2CH2N=C(CH3)C6H 4-2-OH (L3), respectively. The reduction of L1 and L3 with NaBH4 resulted in 4-MeOC6H 4TeCH2CH2NHCH(CH3)C 6H4-2-OH (L2) and 2-HOC6H 4(CH3)CHNHCH2CH2TeCH 2CH2NHCH(CH3)C6H4-2-OH (L4), respectively, which have 1 or 2 chiral centers. The 1H and 13C NMR spectra of L1 to L4 were found to be characteristic. Treatment of L1 with [Ru(p-cymene)CI2]2 resulted in [Ru(p-cymene)(4-MeOC 6H4TeCH2CH2NH2)CI] CI·H2O (1) whereas in the reaction of L2 with [Ru(p-cymene)CI2]2, the p-cymene ligand is lost resulting in [RuCI(L2-H)] (4). The reactions of L1, L3 and L4 with HgBr2 resulted in complexes of the type [HgBr2·(L)2] while Na2PdCI4 reacted with L1 to give [PdCI(L1-H)]. The solid-state structures of L1, L3, 1 and 4 were determined by single-crystal X-ray diffraction studies. The very swift formation of the tellurated amine from a tellurated Schiff base (L1) by hydrolysis has been observed for the first time and has resulted in 1. The Ru-N and Ru-Te bond lengths in 1 are 2.142(3) and 2.6371 (4) A, respectively. The replacement of the p-cymene ligand with a hybrid organotellurium ligand (L2-H), resulting in 4, is also a first example of its kind. The Ru center in 4 has a square-planar geometry, with the Ru-N, Ru-Te, Ru-O and Ru-CI bond lengths being 2.041(6), 2.4983(8), 2.058(5) and 2.308(2) A, respectively. In the crystals of 4 there are secondary intermolecular Te...CI interactions and intermolecular N-H...O hydrogen bonds. This is the first example in which coordinated Te in a complex is engaged in two intermolecular secondary interactions. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004.
